This application claims priority to U.S. Provisional Application Ser. No. 60/718,618, Sep. 20, 2005 and U.S. Provisional Application Ser. No. 60/680,107, May 12, 2005.

FIELD OF THE INVENTION

This invention comprises compounds which inhibit the activity of anti-apoptotic Bcl-2 family protein members, compositions containing the compounds and methods of treating diseases during which are expressed one or more than one of an anti-apoptotic family protein member.

BACKGROUND OF THE INVENTION

Anti-apoptotic Bcl-2 family protein members are associated with a number of diseases and thus are under investigation as potential therapeutic drug targets. These important targets for interventional therapy include, for example, the Bcl-2 family of proteins Bcl-2, Bcl-X_(L) and Bcl-w. Recently inhibitors of Bcl-2 family members have been reported in the literature, see, for example, WO 2005/049594, Oltersdorf, et. al. Nature 2005, 435, 677-681, U.S. Pat. No. 6,720,338 and U.S. Pat. No. 7,030,115. While this art teaches inhibitors having high binding to the target protein, this is only one of many parameters that must be considered as a compound is investigated for further or continued drug development. As part of this development, it is highly desirable to produce compounds that are efficacious in animal models of cancer after oral administration. To achieve this oral efficacy, it is well known in the art that a compound must not only display potent activity against a tumor type or cell line under investigation, but must also achieve acceptable levels of systemic exposure after oral administration. A typical measure of cellular activity is the concentration eliciting 50% cellular effect (EC₅₀). A typical measure of systemic exposure is the area under the curve resulting from graphing the plasma compound concentration after oral administration vs. time (AUC). The ratio between these parameters (AUC/EC₅₀) is well known in the art to constitute a useful pharmacodynamic parameter to predict oral efficacy.

The inventors have discovered that while compounds taught in the art may have either potent cellular efficacies or high systemic exposures after oral administration to animals, they do not possess both properties. This results in a low AUC/EC₅₀ ratio and renders these compounds not orally efficacious. This invention is directed to a series of haloalkylsulonylaryl analogs that demonstrate enhanced and unexpected properties with respect to cellular efficacy and systemic exposure after oral administration in animals. Specifically, compounds of this invention maintain potent cellular efficacy while exhibiting suitable systemic exposure after oral administration to animals. This results in AUC/EC₅₀ ratios significantly higher than that of the compounds taught in the art.

DETAILED DESCRIPTION OF THE INVENTION

Variable moieties of compounds herein are represented by identifiers (capital letters with numerical and/or alphabetical superscripts) and may be specifically embodied.

It is meant to be understood that proper valences are maintained for all moieties and combinations thereof and that monovalent moieties having more than one atom are attached through their left ends.

It is also meant to be understood that a specific embodiment of a variable moiety may be the same or different as another specific embodiment having the same identifier.

The term “antitumorigenesis,” as used herein, means reduction of tumor growth.

Compounds of this invention may contain asymmetrically substituted carbon atoms in the R or S configuration, wherein the terms “R” and “S” are as defined in Pure Appl. Chem. (1976) 45, 13-10. Compounds having asymmetrically substituted carbon atoms with equal amounts of R and S configurations are racemic at those atoms. Atoms having excess of one configuration over the other are assigned the configuration in excess, preferably an excess of about 85%-90%, more preferably an excess of about 95%-99%, and still more preferably an excess greater than about 99%. Accordingly, this invention is meant to embrace racemic mixtures and relative and absolute diastereoisomers of the compounds thereof.

Compounds of this invention may also contain carbon-carbon double bonds or carbon-nitrogen double bonds in the Z or E configuration, in which the term “Z” represents the larger two substituents on the same side of a carbon-carbon or carbon-nitrogen double bond and the term “E” represents the larger two substituents on opposite sides of a carbon-carbon or carbon-nitrogen double bond. The compounds of this invention may also exist as a mixture of “Z” and “E” isomers.

Compounds of this invention may also exist as tautomers or equilibrium mixtures thereof wherein a proton of a compound shifts from one atom to another. Examples of tautomers include, but are not limited to, keto-enol, phenol-keto, oxime-nitroso, nitro-aci, imine-enamine and the like.

Compounds having formula (II) having NH, C(O)OH, OH or SH moieties may have attached thereto prodrug-forming moieties. The prodrug-forming moieties are removed by metabolic processes and release the compounds having the freed NH, C(O)OH, OH or SH in vivo. Prodrugs are useful for adjusting such pharmacokinetic properties of the compounds as solubility and/or hydrophobicity, absorption in the gastrointestinal tract, bioavailability, tissue penetration, and rate of clearance.

Metabolites of compounds having formula (II), produced by in vitro or in vivo metabolic processes, may also have utility for treating diseases associated with expression of an anti-apoptotic family protein member such as of BCl-X_(L) protein, Bcl-2 protein or Bcl-w protein.

A negative control (DMSO, 15 nM BAD peptide, assay buffer) and a positive control (DMSO, 1 nM BAD peptide, 6 nM Bcl-X_(L), assay buffer) were used to determine the range of the assay. Polarization was measured at room temperature using a continuous Fluorescein lamp (excitation 485 nm, emission 530 nm). Percentage of inhibition was determined by (1−((mP value of well-negative control)/range))×100%. The results are shown in TABLE 1.

Binding affinity of compounds having formula (II) to Bcl-2 protein is indicia of their inhibition of the activity of this protein. To determine the binding affinity of compounds having formula (II) to Bcl-2, representative examples were diluted in DMSO to concentrations between 10 μM and 10 pM and added to each well of a 96-well microtiter plate. A mixture comprising 125 L per well of assay buffer (20 mM phosphate buffer (pH 7.4), 1 mM EDTA, 50 mM NaCl, 0.05% PF-68), 10 nM of Bcl-2 protein (prepared according to the procedure described in PNAS 2001, 98, 3012-3017), 1 nM fluorescein-labeled BAX peptide (prepared in-house) and the DMSO solution of the representative EXAMPLE was shaken for 2 minutes and placed in a LJL Analyst (LJL Bio Systems, CA. Polarization was measured at room temperature using a continuous Fluorescein lamp (excitation 485 nm, emission 530 nm). The results are also shown in TABLE 1.

These data demonstrate the utility of compounds having formula (II) as binders to and inhibitors of anti-apopotic BCl-X_(L) protein and anti-apopotic Bcl-2.

It is expected that, because compounds having formula (II) bind to and inhibit the activity of BCl-X_(L) and Bcl-2, they would also have utility as inhibitors of anti-apopotic family protein members having close structural homology to BCl-X_(L) and Bcl-2 such as, for example, anti-apopotic Bcl-w protein.

Accordingly, compounds having formula (II) are expected to have utility in treatment of diseases during which anti-apopotic Bcl-X_(L) protein, anti-apopotic Bcl-2 protein, anti-apopotic Bcl-w protein or a combination thereof, are expressed.

Determination of Cellular Efficacy in Human Tumor Cell Line

NCI-H146 (ATCC, Manassas, Va.) human small cell lung carcinoma cells were plated 50,000 cells per well in 96-well tissue culture plates in a total volume of 100 μL tissue culture medium supplemented with 10% human serum (Invitrogen, Carlsbad, Calif.) instead of fetal bovine serum and treated with a 2-fold serial dilution of the compounds of interest from 10 μM to 0.020 μM. Each concentration was tested in duplicate at least 3 separate times. The number of viable cells following 48 hours of compound treatment was determined using the CellTiter 96® AQ_(ueous) non-radioactive cell proliferation MTS assay according to manufacturer's recommendations (Promega Corp., Madison, Wis.). The results are also shown in TABLE 1.

Pharmacokinetic Evaluation of Selected Compounds in Rat

The pharmacokinetic behavior of compounds of this invention was determined following a single 2 mg/kg intravenous or 5 mg/kg oral dose in male Sprague-Dawley derived rats (n=3 per group). The compounds were prepared as 2 mg/mL solution in a 10% DMSO in PEG-400 formulation for both oral and intravenous administration. The 1 mL/kg intravenous dose was administered as a slow bolus (about 1-2 minutes) in the jugular vein of a rat under light ether anesthetic. The oral dose was administered by gavage. Serial blood samples were obtained from a tail vein of each rat prior 0.1 (IV only), 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8 and 24 hours after dosing. The heparinized samples were thoroughly mixed and placed in an ice bath. Plasma was separated by centrifugation and stored frozen prior to analysis. The results are also shown in TABLE 1.

The compounds of interest were separated from the plasma using protein precipitation with acetonitrile. A plasma (100-200 μL, sample or spiked standard) aliquot was combined with 50 μL of internal standard (structurally related analog prepared in acetonitrile) and 1 ml acetonitrile in a 96-well polypropylene deep well plate. The plates were vortexed for 30 seconds followed by centrifugation (3500 rpm×15 minutes, 4° C.). In an automated manner, the supernatant was transferred to a clean 96-well plate. The samples were evaporated to near dryness on a Micro-Vap™ under a stream of dry nitrogen over low heat (˜37° C.). The samples were reconstituted vortexing with 0.2 mL 5% DMSO in acetonitrile. A 0.1-0.2 ml aliquot of acetonitrile: 0.1% trifluoroacetic acid (20:80, by volume) was added to each well, followed by an additional 30 second vortexing. The plates were centrifuged (3500 rpm×15 minutes, 4° C.) prior to HPLC-MS/MS analysis. Samples were analyzed simultaneously with spiked plasma standards. All samples from each study were analyzed as a single batch on the LC-MS/MS.

The compounds of interest and the internal standard were separated from each other and co-extracted contaminants on a 50×3 mm Keystone Betasil CN 5 μm column with an acetonitrile: 0.1% trifluoroacetic acid mobile phase (50:50, by volume) at a flow rate of 0.7 ml/min. Analysis was performed on a Sciex API 300™ Biomolecular Mass Analyzer using a heated nebulizer interface. Peak areas of the title compounds and internal standards were determined using the Sciex MacQuan™ software. Calibration curves were derived from peak area ratio (parent drug/internal standard) of the spiked rat plasma standards using least squares linear regression of the ratio versus the theoretical concentration. The methods were generally linear over the range of the standard curve (correlation coefficients>0.99) with an estimated quantitation limit of 0.01 μg/mL. The plasma concentration data for each animal were submitted to multi-exponential curve fitting using WinNonlin. The area under the plasma concentration-time curve from 0 to t hours (time of the last measurable plasma concentration) after dosing (AUC_(0-t)) was calculated using the linear trapezoidal rule for the plasma concentration-time profiles. The residual area extrapolated to infinity, determined as the final measured plasma concentration (C_(t)) divided by the terminal elimination rate constant (β), was added to AUC_(0-t) to produce the total area under the curve. The results are also shown in TABLE 1. TABLE 1 AUC/ Ex.

The compounds of the present invention were also tested against compounds disclosed in WO 2005/049594, identified herein as EXAMPLES A-L, by determining the ratio of systemic exposure to cellular efficacy. This measure, sometimes reported as AUC/EC₅₀, is well known to those skilled in the art of pharmaceutical drug discovery and drug development as a useful pharmacodynamic predictor of oral efficacy.

The examples of the present invention and compounds disclosed in WO 2005/049594 were both tested H146 cellular assay and evaluated for oral pharmacokinetic properties in rat, both as previously described herein. The results are shown in TABLES 2 and 3. As can be seen with reference to the data, the compounds of the present invention have a more preferred pharmacodynamic profile as compared to the compounds known in the art. From these results a number of observations can be drawn. It can be observed that the compounds having a NO₂ moiety at position W¹ tend to have good to excellent cellular potency. However, when the pharmacokinetic properties of these same compounds are determined, it can be seen that the systemic exposure after oral administration is poor, resulting in AUC/EC₅₀ ratios of from 0.5 to 19.7. On the other hand, when compounds having a CF₃ or CN moiety at position W¹ are tested in the cellular assay, the results demonstrate that these derivatives have relatively poor cellular efficacy while at the same time having suitable systemic exposure after oral administration. Again, this combination provides overall AUC/EC₅₀ ratios from about 2.8 to about <7.4. Surprisingly, compounds of the present invention demonstrate cellular efficacy on par with compounds having an NO₂ moiety while maintaining suitable systemic exposure after oral administration. The resulting AUC/EC₅₀ ratios for the compounds of the invention are from about 20 to about 554. TABLE 2
